=== New from 22 July 2022, a codec2 repeater ===========
# Saves the data after FEC and retransmits when triggered.

Parrot22jul2022.zip runs on the unmodified Codec2 library.

Beacons every 3 mins (settable).  callsign in mode 700D or 700E

Linux Install notes (any Raspberry Pi or clone or PC):
  
  Download the Codec2 library
  git clone https://github.com/drowe67/codec2
  cd codec2; mkdir build1; cd build1; cmake ../ ; make install
  Download  my latest ParrotXXX file here, unzip.
  cd freebeacon; mkdir build1; cd build1; cmake ../ ; make freebeacon

  Some new options added, others are the same as "freebeacon".

--------- old --------------
  git clone https://github.com/drowe67/freebeacon
  unzip ParrotNNxxx2020.zip
  This replaces CMakeLists.txt build file and adds "parrot.c"
--------- extra old --------------
A Codec2-dev library (modified) that WORKS with my "parrot" repeater.
   c2dev3955.tgz 
   parrot20190811.tgz  play700C
My mods do not affect the FreeDV GUI app.

Later Codec2-dev versions from GitHub are not as good Rx wise and crash
on transmit.


A Linux application, command line, uses both channels of a stereo sound dongle,
Left for Rx, Right for Tx. Thus no audio switching required.
"should" work on all Codec2-dev libraries.
I use a Creative "SoundBlaster Play! 3" available world-wide.
